46 Capt. T. Broun on new 



slender and elongate ; basal joint stout, sliglitly arclied ; 

 2nd longer tlian broad, about half as long as the basal 

 one; 3rd rather longer than the contiguous ones ; joints 

 5-8 elongate, the last, however, distinctly shorter and 

 stouter than the 5th ; terminal three a little expanded, 

 10th slightly broader than 9th. Leffs simple, unarmed ; the 

 anterior tibise on the inside, below the mifhlle, with a wide 

 excision. Tarsi stout, each of the basal four joints trans- 

 verse, the first largest, the fifth about half the length of 

 the others conjointly ; claws small and slender. 



Head subquadrate, moderately rounded and narrowed in 

 front. Clypewi prolonged anteriorly. Eyes coarsely facetted, 

 subrotundate, only slightly convex. Thorax notched later- 

 ally. Elytra subquadrate, costate. Hind body gradually 

 attenuated, not longer than the elytra, the basal three 

 segments strongly margin ated. 



The characters given above show that this genus cannot 

 be associated with Omalium, in which the terminal joint of 

 the tarsi equals the basal four taken together, and the 

 clypeus is not produced so as to cover the mandibles. In 

 Micropeplus the body is similarly costate, but the tarsi are 

 only tri-articulate, and the antennae are nine-jointed and 

 abruply clavate. It ma}'^ be located between these two 

 genera, but, even there, on account of the notch along the 

 inner face of the front tibiae similar to that seen in the 

 Carabidse, it will occupy an isolated position. 



Enpsoriis costatus, sp. n. 



Body slightly nitid, almost uniformly pale brown, spar- 

 ingly clothed with decumbent pallid setae. 



Head smaller than thorax, Avith two deep longitudinal 

 cavities, the margins and central portion asperate. Thorax 

 about as long as it is broad, its sides explanate and of some- 

 what rounded outline, interrupted, however, by three or 

 four unequal indentations, so that the basal portion appears 

 as if abruptly constricted ; there are two strong, but not 

 quite straight, discoidal costse, which seem rough, but the 

 dilated sides are nearly smooth and shining and very sparsely 

 setose. Elytra just as broad as they are long, almost 

 parallel-sided, shoulders rounded ; apices bisinuate, so that 

 tlie true basal segment of the abdomen may be detected 

 from above ; they bear three costtc, the suture forming the 

 central one, and there is a curvate humeral elevation on 

 each; their whole surface is coarsely punctured. Hind 

 body transversely convex ; the four fully-exposed segments
